The bios nowadays is not working fine any longer, and the laptop doesn't boot, clearly.

I would be very happy to get some kind of help, and since I am a newbie, it would be great if you feel ready even just to address me to the most relevant web pages.

The job is focused on flashing a 16 pin mx bios chip on a lenovo laptop model x200, for the use of a specific firmware called LibreBoot.

Many thanks again,

Sandro
